Absolutely! I have the utmost respect for all those that have and do serve(d). My appreciation to your dad. I knew a guy, just out of high school, a real PITA to be around, rude, nasty and plain mean. He chose to join the AF. His first trip home, I saw him. I could NOT believe the change in that guy. He was polite, pleasant and respectful. He was a man.
Hopefully, you still have the 510 adapter for your Zeus, if not let me know. I purchased some a while back, since the first one I got didn't have one, and they threw in extras due to delayed shipping. If it turns out you still don't like it, keep me in my mind, it's one of my faves. Hope it works out well for you, though. Life deserves good vapes.
